Abstract
The combination of a microencapsulated hydrosilylation catalyst selected from the group consisting of metals from the platinum group of the periodic table and compounds of these metals and a known inhibitor for this type of catalyst impart excellent storage stability to organosiloxane compositions that cure by a hydrosilation reaction while enabling these compositions to rapidly cure at temperatures above the softening temperature of the thermoplastic resin used to encapsulate the hydrosilylation catalyst. The curing rate of the composition is faster relative to compositions containing the microencapsulated catalyst without the catalyst inhibitor.
